Worst possible customer service

This is the worst customer experience I've ever experienced. I ordered a cologne that was advertised as Au de Parfum but received the Au de Toilette. First of all, they never respond to their mails, it has been 5 months and 4 emails but no response. Secondly when I eventually managed to find their phone number somewhere on the internet, they keep promising me that they have issued the instruction for my cologne to be collected, and then they will replace, but no collection has ever taken place and they never call back. It's simple, do not shop from this place.
